Abstract: The invention proposes a transverse flux machine, in particular a unipolar transverse flux machine, with at least one stator module contained in a housing composed of two axially joined housing parts and having an annular coil disposed concentric to the housing axis as well as stator elements that embrace this annular coil from the outside and inside. For ease of assembly of the individual parts and for a precisely toleranced maintenance of a small air gap between the stator and the rotor, clamps that protrude axially from the respective housing parts oriented toward each other are provided for the stator elements and have positioning elements for securing them in the radial direction.

Abstract: The invention relates to an electromechanical wheel brake device (10), with an electric motor (18) that can press a frictional brake lining (14) against a brake body (16) (brake disk) by means of a reduction gear (34) (planetary gear) and a rotation/translation conversion gear (48) (ball screw). The invention proposes embodying the electric motor (18) as a transverse flux motor (18) with three phase windings (21); each phase winding (21) has a circular, annular excitation winding (22) that is disposed inside U-shaped yokes (24), which are distributed over the circumference of the excitation winding (22). This embodiment of the electric motor (18) permits a compact design of the electric motor (18) in an annular, hollow shaft design so that the reduction gear (34) and the rotation/translation conversion gear (48) can be disposed at least partially inside the electric motor (18).

Abstract: In a unipolar transverse flux machine, to achieve a modular construction, which is favorable from a production standpoint, the stator (11) and the rotor (12) have an equal number of identical stator modules (14) and rotor modules (15); the rotor modules (15) are firmly seated, in alignment with one another, on the rotor shaft (13), and the stator modules (14) are rotated by a rotational angle from one another in the housing (10). When there are two stator modules (14), the rotational angle is 90° electrically, and when there are m stator modules (14), the rotational angle is 360°/m electrically, where m is an integer and is greater than 2. Each stator module (14) has an annular coil (23), disposed coaxially to the rotor axis (19), and U-shaped stator yokes (24) that fit over the annular coil, along with short-circuit elements (25) disposed between the stator yokes.

Abstract: In a unipolar transversal flux machine, in particular a motor, having a rotor (12), which is comprised of two coaxial, ferromagnetic, toothed rotor rings (14, 15), and a permanent magnet ring (16), which is magnetized in an axially unipolar fashion and is clamped axially between these rotor rings (14, 15), and having a stator (11), which is concentric to the rotor shaft (13) and has U-shaped stator yokes (19) that represent the magnet poles, yoke elements (20), and a stator winding (21), in order to achieve an extremely flat design and to assure a definite start in a particular direction, the stator winding (21) is embodied with two coils (22, 23), whose one coil side (221, 231) extends respectively over a group of stator yokes (19) and yoke elements (20) arranged in succession in the circumference direction, along the side of the yoke elements (20) remote from the rotor shaft (13), between the yoke legs (19), where the group spanned by the coil side (221) of the one coil (22) is disposed spatially offset on
